Baryogenesis is believed to occur at, or before the Universe underwent electroweak phase transition [1]} at a temperature \(T\simeq 130\)   GeV, about 1000 times larger compared to temperature range we consider in this work. However, heavy bottom flavor decoupling near to deconfined quark-gluon plasma (QGP) transformation to hadron gas (HG) phase just at the upper range of our present consideration may offer alternate opportunity [2]}. Complementing this work we explore here strange meson decay and production reactions that lead to strangeness flavor decoupling after formation of HG phase. We plan to return to the case of charm flavor in another research cycle. However, our finding that the strange meson decoupling occurs just below antibaryon decoupling and disappearance implies that we return to the case of strangeness including reactions involving (anti)hyperons.
